I do not take credit for this nor did i make this script at all i just modified it.   THIS NPC REQUIRES FLUX CONTROL PANEL OR IT WILL NOT WORK. i myself was asking for someone to modify an Npc to be able to accept cash points in game  but i also decided it would be ideal to give you both options so it was edited to not only give you the option to redeem cash points but also maintain its core function of allowing a player to still redeem items purchased on the web-store.
